Sweet Sorghum is a sorghum grass variety with a high sugar content. It has better growing conditions than many other crops in drier and warmer environments and is mainly used in feed, silage and syrup production. Sweet sorghum syrup is called "sorghum honey" in some parts of the United States, although in most parts of the country the word "honey" usually refers to the syrup byproduct extracted from sugar cane or sugar beets.
Sweet sorghum has been widely grown in the United States since the 1850s, primarily as a sweetener, particularly in the form of sorghum syrup. In 1857, James F. C. Hyde wrote: "The importance of the subject of sugar production to us as a people cannot be underestimated, for no country in the world can equal the consumption of the United States." As the British West Indies Decreased sugar production in the Islands and increased demand for round candies and jams, coupled with rising sugar prices, led the United States to search for sugar crops that could be produced in the north. "Chinese sugar cane" is considered a crop with good yields in the region.
In the early 1860s, the American Civil War not only disrupted internal and maritime commerce but also diverted goods from civilian to military use, making certain food and fiber supplies unreliable and expensive. Especially in the South, cane sugar and molasses shipped from the Caribbean became expensive and scarce due to the Union naval blockade. Under these circumstances, some farms began growing sweet sorghum to produce syrup as a substitute for cane sugar and molasses, which played an important role in solidifying sweet sorghum's place in Southern food culture.
Sweet sorghum also gained use in the North as families fighting slavery resisted the use of sweeteners produced with slave labor.
By the early 1900s, the United States was producing 20 million gallons (about 76,000 cubic meters) of sweet sorghum syrup annually. However, making sorghum syrup (like sugar cane) is quite labor intensive. After World War II, as farm labor decreased, sorghum syrup production decreased significantly, and now less than 1 million gallons (about 3,800 cubic meters) are produced in the United States annually. Notably, in India, sweet sorghum was introduced in the early 1970s by the Nimbkar Agricultural Research Institute for the production of ethanol and syrup.
Sweet sorghum syrup displays good antioxidant properties and shows broad application potential in the food, beverage and pharmaceutical industries.
Currently, sweet sorghum is grown on a large scale in states such as Alabama, Arkansas, Georgia, Iowa, Kentucky, Mississippi, North Carolina, Missouri and Tennessee. Sweet sorghum syrup and warm biscuits are a traditional breakfast pairing in the South. In the United States, sweet sorghum has been mainly used for feed and silage since the 1950s, and its cultivation is mainly concentrated in arid plains areas such as Texas, Kansas and Nebraska.
In addition to its use as food, the uses of sweet sorghum are gradually expanding in other fields. It becomes the main source of feed for livestock cattle and also excels in environmental sustainability due to its yield and environmental adaptability. Recent research shows that growing sweet sorghum instead of grain sorghum can increase farmers' income by about $40 per hectare because sweet sorghum provides food, feed and fuel.
Sweet sorghum's role is likely to continue to expand as new generations of ethanol-making technologies continue to be developed. Globally, with the expansion of dry areas and the increase in demand for cash crops, sweet sorghum has gradually become a potential crop for agricultural production in various countries. In the traditional diet of the South, sweet sorghum syrup has become a stable delicacy. Coupled with its functional advantages, we can look forward to its future development. But in today's increasingly diversified food culture, can sweet sorghum continue to play its unique role in the global food market?
